IMPROVEMENT IN THlLL-COUPLINGS.

Specilcation forming part of Letters Patent No. 207,587, dated September3, 1878; application filed January 25, 1878.

To all whom it may concern:

Be it known that I, HENRY E. BRAUNFELD, of the city and county ofBaltimore, and State of Maryland, have invented a new land usefulImprovement in Shaft-Couplings, which improvement is fully set forth inthe following specication and accompanying drawings, in which- Figure lis a side elevation of the coupling embodying my invention. Fig. 2 is atop or plan view thereof. Fig. 3 is a central vertical longitudinalsection thereof. Fig. 4 is a central vertical longitudinal section of amodification thereof. Fig. 5 is a view of a detached part. Y

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a hinged clasp for holding the head of thethill or shaft iron to the clip, in combination with a clevis for firmlysecuring the clasp.

It also consists in providing the clevis with a screw which engages withthe head of the clasp, and has connected to it a strap which is attachedto the shaft as a means of safety in the event of breakage of the iron.

It also consists of means of taking up lateral strain and preventingbreakage of the clasp and clevis.

Referring to the drawings, A represents the neck of the coupling, to beattached to the shaft B in any desired manner, and C the clip, to besecured to the axle as usual. To the upper portion ofthe clip there ishinged a horizontallyftrran ged clasp, D, the inner face of which has apartial concavity, which, with a partial concavity on the upper face ofthe clip, forms a socket for the head A of the couping.

E represents a latch or elevis, which extends vertically, and is hingedto the side of the clip, so that its upper bar overhangs the free end ofthe clasp D. To said bar is fitted a screw, F, which is adapted toengage with the head a of the clasp D, and the` upper or outer end ofsaid screw is formed with an eye, F', to which is connected a strap, G,secured to the shaft or shaft and neck between the head A and forwardend of the neck.

Encircling the head A is a rubber packing, H, which is of the form of apartial cylinder, whereby, when the clasp D is forced into position andcompresses the packing, the latter will yield and spread over the hea-d,so that the elasticity of the rubber is not destroyed, and there isyielding connection of the head and clip, and rattling of the couplingis prevented.

In Fig. l the head A projects through openings at the sides of the clipand clasp, and at said sides are forks extending to the neck of thecoupling. In Fig. 4, an opening is made in clasp D, and into the sameprojects the neck directly attached to the head.

The operation is as follows: When the shafts are to be detached from theaxle the strap is loosed and the screw F is turned so as .to clear thehead a of the clasp 5 then swing out the latch E and throw up theclasp'D. This uncovers the head A', and permits the entire displacementof the latter and separation of the shaft. v

In order to couple the parts apply the head A', lower the clasp D, raisethe latch' E over the clasp, and turn down the screw F' so as to takefirm hold of the head of the clasp. This prevents the opening of thelatch and consequent raising of the clasp, and thus vthe head issecurely connected to the clip without liability of accidentaldisplacement of the shaft, being thereby reliably coupled with the axle.

The upper portion, I), of' the clip adjacent to the latch E is formedwith a notch, d, into which enters the tongue e of the clasp, with whichthe head a is formed. In the event of lateral strain on the head A orthe clasp D, the tongue c of the latter is held by the walls of thenotch, and thus the breakage of the clasp and latch is prevented.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

. 1. The clip with the clasp D, in combination with the locking-clevisE, substantially as and for the purpose set forth.

2. The clip C and clasp D, in combination with the locking-clevis E,carrying the screw F and the safety-strap G, substantially as and forthe purpose set forth.

3. The clasp D with tongue e,iu combina-Y tion Vwith the clip O withnotch d, substan tially as and for the purpose set forth.
